Notes Mode

Notes mode is an (X)Emacs mode for taking notes. In particular, it is
designed for taking notes on a laptop during presentations (e.g.,
lectures or conferences). Notes mode has three basic functions:

It colorizes the notes, using a simple and fairly transparent markup
language. It uses the x-symbol minor mode to render special
characters, using LaTeX encodings (e.g., "lambda" and "to"). It uses
the x-render minor mode to render graphs, plots, and syntax trees as
inline images Notes mode does not require x-symbol mode or x-render
mode; but if they are unavailable, then notes mode will not perform
the corresponding function.

Notes mode is accompanied by parsenotes, a python script that converts
notes files to pdf files (using LaTeX). This allows you to generate
high quality output from your notes files. See some of my class notes
for examples of the pdf output.
